' SNOW-ROAD-MAKING MACHINE.

Specification of Letters Patent.

Patented Oct. 19, 1909.

To all whom it may concern:

Be it known that we, FRANK ALEXANDER and BENJAMIN A. MUNoIL, citizens ofthe United States, residing at Paul Smiths, in the county of Franklinand State of New York, have invented a new and useful Snow- Road-MakingMachine, of which the following is a specification.

This invention relates to a machine which makes a road on snow bydragging a weighted platform over the same.

The object of the present invention is to provide a machine of this kindwhich can be operated in any depth of snow, and which can also beemployed for packing snow on streets or roads to render the samepassable for sleighs, teams and pedestrians.

Another object of the invention is to provide means for leveling offholes and hollows, and also to form a foot path on both sides of theroad.

The invention also has for its object to provide a road-making machineof the kind stated, which is simple in structure, and easily operated.

With the foregoing objects in view, the invention consists in a novelconstruction and arrangement of parts to be hereinafter described andclaimed, reference being had to the drawing hereto annexed in which-Figure 1 is a plan View of the machine. Fig. 2 is a side elevation. Fig.8 is a central longitudinal section. Fig. 4 is a section on the line 4.4of Fig. l.

The machine is in the form of a sled, the runners of which are indicatedat 5. Extending between said runners, at the front end thereof, andmounted therein so as to be free to rock, is a cross-bar 6 to which thedraft pole or tongue 7 is connected. The draft animals are connected tothis pole or tongue in the ordinary manner.

The runners 5 are connected at their rear ends by a cross-bar 8 havingdownturned ends 9 which are bolted or-otherwise suitably fastened to therunners on the outside thereof. By these downturned ends the cross-baris spaced a suitable distance above the top of the runners, and saidcross-bar carries seats 10 for the operators, said seats being securedto the cross-bar adjacent to the ends thereof. At the middle of thecross-bar is mounted a pair of uprights 11 which are spaced apart, andwhich are for a purpose to be presently described.

Extending between the runners 5 about midway between the ends thereof,and secured thereto in any suitable manner, is a rod 12 which carries aplatform 13. To the top of the platform, adjacent to the side edgesthereof, are secured metal strips 14 which are bent at one end into eyes15 through which the rod 12 passes, whereby the platform is hingedlyconnected to and supported by the said rod. The bottom of this platformis covered with a metal sheathing 16. Extending across the top of theplatform at the free end thereof is a strip 17.

In front of the platform .13 islocated a scraper comprising a pair ofrearwardly diverging scraper-blades 18 secured to a cross-bar 19extending between and mounted in the runners, said cross-bar being somounted as to be free to rock. The scraper-blades are connected at theirfront ends by a shank 20 by means of which they are secured to thecross-bar 19, bolts 21 being passed through said parts and secured bynuts screwed thereon. The scraper-blades are slightly forwardly inclinedin the direction of their lower ends, and their lower edges are alsocurved.

Extending rearwardly from the cross-bar 19 is a guard plate 22 whichcovers the front end of the scraper-blades, and which serves to preventthe snow from being thrown on the platform 13. To the scraper-blades aresecured straps 22 which extend over the top of the guard plate, and aresecured on top of the cross-bar 19. On top of the guardplate, adjacentto the rear edge thereof, and extending between the straps 22, is astrip 23 which serves as a brace.

Passing through openings in the guard plate 22 and the strip 23, is astem 24, which is screw-threaded to receive nuts 25 and 26, thefirst-mentioned nut being screwed on the stem to engage the bottom ofthe guard plate 22, and the last mentioned nut being screwed on the stemto engage the top of the strip 23, whereby said stem is securely held inplace. The stem rises from the strip 23 a suitable distance, and itsupper end is also screw-threaded to receive the nut 27.

At 28 is indicated a lever having at one end ahook 29 which engages aneye 29 on the butt end of the tongue 7. The other end of the leverenters between the uprights 11, and is held by a bolt 30 passingtransversely therethrough. Intermediate its ends, the lever is formedwith an ofi-set 31, and secured to the lever adjacent to the ends ofsaid off-set portion is a strip 32.. The off-set 31 andrstrip 32 form aslot inwhich the stem 24 is received. The upper edge of the lever isengaged by the nut 27,: and between the 5 lower edge of the lever andthe nut 26 a spring 33, is-vcoiledaround the stem, awasher 3'4 beln'ginterposed between one end of the spring and the lever.

In the operation of the machine, th'e'plat- -1-0 zform l3' -is loadedwith-someheav-y material I 'i .such 'vas pig iron, stone; or lead,whichever is imost convenient' in the locality where the v mach-ine is-in user-- The platform is pitched aat r-an angle which-throws all theWeight v 15 cona Tsmarltsurface at the rear end thereof, and whensaidplatforni is'dragged over the isurfaceiiof the snow', the latteris-packed :ihard enough to form a road or path! The m 'gst'ri'p ih zprevents the-weights from rolling r 2 the platform The {scraper-bladesl8 clean the track where thehorses and sleighs r n'travel; and throwthesnow on the outside of each tra'ck, :thllS; making a shoulder toprevent sleighsfromslui-ng and the horses i'2 wfromzsl-umping, and ahard: foot path isalsoformed on iboth sides of the track. -The tion whenthe machine is used for'thedatter That is" claimed is i thereby,scraper-s rocking support-for said from the support, and passin'gthrough the stem-between the support and the lever, and
